fluent coeff

In Fluent, a CFD (Computational Fluid Dynamics) software, "coeff" likely refers to coefficients used in the governing equations to model various physical phenomena. Here's a brief explanation:

1. Evaporation[^1]: In Fluent, evaporation is often modeled as a phase change from the liquid to the gaseous phase, where the mass transfer coefficient (or evaporation rate) is an important coefficient that determines how quickly the liquid evaporates. It affects the energy balance and the conservation of mass.

2. Phase Scaling Factors: The terms "From Phase Scaling Factor" (Cl) and "To Phase Scaling Factor" (Cv) are typically associated with convective heat transfer coefficients between phases. They represent the efficiency of heat transfer between a fluid and its interface with another phase, like evaporation or condensation. These coefficients can be user-defined or calculated using empirical correlations or theoretical models.

To demonstrate in Fluent, you would typically set these coefficients in the boundary conditions or physics settings for the appropriate surface, adjusting them to reflect the real-world properties of your system or following recommended correlations for the specific flow conditions.
